WVILLIAM A. PAINTER, OF ALLEGHENY, PENNSYLVANIA, ASSIGNOR TO PITTSBURGH LAMP, BRASS & GLASS COMPANY, OF PITTSBURG, PENN SYLVANIA, A CORPORATION OF NEIN JERSEY.

LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 774,602, dated November'8, 1904. Application filed January 11, 1904. Serial No. $8,464. (No model.)

To all whom, it Wtay concern:

Be it known that I, l/VILLIAH A. PAINTER, of Allegheny, in the county of Allegheny, State of Pennsylvania, have invented a new and use-- ful Lamp-Burner, of which the following is a full, clear, and exact description, reference be mechanism is provided for lifting the wick;

and the invention is designed to provide a simple, cheap, and eflicient constructionoof the wick-lifting apparatus and also an improved arrangement of the gallery lift-tube.

In the drawings, 2 represents the lower outer shell portion of the burner, which is preferably perforated, as shown, and is provided with a central wick-tube 3. In the wicktube is located the wick-lifter 4, which may be of skeleton-tube form and provided with upper slotted spring-clips 5 for the wick of ordinary form.

The rack 6 is secured to the lower part-of the lifter and is bent outwardly slightly and extends up through a loose guide 7, fitted into a hole in the lower part of the burner-shell. This guide, as shown in Fig. 4, consists of a bent strip of U form, having a projecting per forated lug 8. The other lug of the U may have a struck-up projection 9 to rest against the wick-tube and space the guide. The hole in the lug 8 is in line with the bearing-tube 10 for the stem 11 of the wick-shaft, which shaft extends through the hole and has a squared or angular portion, upon which slips the pinion 12, which engages the rack. Beyond the squared or angular portion the shaft is turned down to a small cylindrical form, as shown in Fig. 3, and this stub end projects through a hole in the wick-tube. The wicktube around this hole is pressed outwardly slightly, and the end of the wick-shaft is upset, so as to form a countersunk head within the recess. It will be noted that the shoulder on the wick-shaft at the angular portion prevents inward movement of the shaft, while the upset-inner end prevents downward motion, and at the same time the wick-lifter is not interfered with, as a countersunk bearing is afiorded for the inner expanded end of the shaft.

The tube or bearing for the wick-shaft is soldered in the receiving-hole and the burnershell, and in assemblingthe parts the rackguide is dropped into its hole, and the wickshaft holds it in position while allowing it to adjust itself. I'thus not only avoid soldering or securing the rack-guide firmly in place, but on account of it being loosely held it will accommodate itself and prevent binding.

The'side of the wick-tube is provided with a pin or lug 13, which moves through an outwardly-pressed portion of the gallery lift-tube 14 and into the double-head bayonet-slot 15. This gallery lift-tube is provided at'its upper end with an outwardly-bent lug l6, which when the parts are locked together by the bayonet-joint will register with the rack and act as a stop therefor to prevent the wick- .lifter being raised too far that is, so far that the spring-clips of the lifter would pass above the upper end of thewick-tube.

The advantages of my invention result from the simple, cheap, and efficient construction of the wick-lifting device and also from the lug-shaped fender on the lift-tube, which registers with the rack when the parts are locked together.

Many variations may be made in the form and arrangement of the burner and its parts without departing from my invention.

I claim 1. In a lamp-burner, a burner-shell, a lifting-rack, a loose guide therefor extending through a hole in the burner-shell, and a wickshaft extending through a hole in the guide and holding it in place; substantially as described. J

2. In a lamp-burner, a wick-tube having an outwardly-struck recess in its side, and an aperture in the bottom of the recess, a wick-raising shaft extending through the aperture and having an inner head Within the recess, and an outer bearing for the Wiclcshaft; substantially as described.

3. In a lamp-burner a Wicleraising shaft having a larger cylindrical portion extending through its bearing and an angular portion, a pinion on said angular portion and a reduced portion extending through a hole in the Wicktube and enlarged at its inner end; substantially as described.

4. A lamp-burner having a burner-shell, a fixed tubular guide in said shell, a Wick-shaft extending through the guide, a rack-guide having a hole through Which the Wick-shaft extends, and a countersunk recess in the Wicktube receiving the enlarged end of the Wickshaft; substantially as described.

5. A lamp-burner having a rack, a Wickshaft, and a rack-guide loosely held in place by engagement with the Wick-shaft, said guide extending through a hole in the burner-shell; substantially as described.

6. A lamp-burner having a burner-shell, a

fixed tubular guide therein, a Wick-shaft extending through the guide and having an angular portion, a pinion slipped on said angular portion, the end of the Wick-shaft extending through the Wick-tube and having an enlarged portion in a countersunk recess of the tube, a rack engaging the pinion and a rack-guide loosely fitted in a hole in the burner-shell and having a hole through Which the cylindrical portion of the Wick-shaft extends; substantially as described.

7. A lamp-burner having a rack-lifting device. a Wick-tube, a gallery lift-tube having detachable locking connection With the Wicktube and a lateral lug on the lift-tube and arranged to register with, and act as a stop for, the rack When the parts are locked; substantially as described.

In testimony whereof I have hereunto set my hand.

WILLIAM A. PAINTER.
